President's Day Weekend is always one of the busiest weekends of the year at Colorado's ski areas, and this year snowy conditions could make it a challenging drive for Coloradans from the Front Range who are hoping to visit the resorts.

Last month, over 1 million vehicles passed through the Eisenhower-Johnson Memorial Tunnel, and CDOT is expecting at least 1 million more this month.

As thousands are expected to hit the slopes over President's Day weekend, the Colorado Department of Transportation, also known as CDOT, says travel through the mountains will be hazardous.
